Research Symposium
Retinal pigmented epithelium (RPE) cells are located between the choroid and photoreceptors within the eye and are essential to provide nutrients from blood to rods and cones, as well retinoids of the visual cycle. Vision loss and various ocular diseases are attributable to the degeneration or dysfunction of the RPE cells, leading to blindness.One of the major ocular problem from RPE dysfunction is macular degeneration. Age-related macular degeneration (AMD) can be frequently diagnosed in patients over the age of 60. In the early stages of AMD, some symptoms may not be noticeable but will lead to vision loss in both …
Precise Method To Identify Kinase Drug Targets In Complex Diseases: The First Step Towards Sustainable And Effective Treatment, Hasbanny Irisson, Marzieh Ayati
Precise Method To Identify Kinase Drug Targets In Complex Diseases: The First Step Towards Sustainable And Effective Treatment, Hasbanny Irisson, Marzieh Ayati
Research Symposium
Background: Kinases are enzymes that have proven to be important drug targets due to their role in critical biological mechanisms such as phosphorylation. Phosphorylation happens when a kinase catalyzes the transfer of a phosphate group to a protein in a phosphorylated site, which then becomes known as the substrate of the kinase. Any dysregulation of protein phosphorylation causes a wide range of complex diseases including cancer. Thus, discovering the links between kinases and their substrates (i.e. predicting kinase-substrate associations (KSAs)) is crucial in developing effective and sustainable treatments. Presently, less than 5% of phosphorylated sites have an associated kinase, and …

Research Symposium
Pancreatic cancer (PanCa) is a third leading cause of cancer related deaths in US. Unlike other cancers, PanCa is highly resistant to TNF-related apoptosis-inducing ligand (TRAIL) that emerges as one of the most-promising therapy in clinical trials. Our group has previously identified microRNA-145 (miR-145) is downregulated in PanCa, the restoration of which inhibits tumor growth and enhances gemcitabine sensitivity. In this study, we have observed that miR-145 restoration in PanCa cells renders them sensitive to TRAIL treatment. Therefore, we have engineered unique superparamagnetic nanoparticles (SPs) for co-delivering miR-145 and TRAIL in PanCa for improving their therapeutic response to TRAIL. The …

Identification And Characterization Of Anticancer Potential Of A Novel Small Molecule, Mortaparibmild, Hazna Noor Meidinna, Anissa Nofita Sari, Sunil C. Kaul, Renu Wadhwa
Research Symposium
Background: The development of new anticancer drugs and treatment modalities form a priority research field. The tumor suppressor protein p53 is frequently mutated or functionally inactivated in a large variety of cancers. Its inactivation by mortalin, a member of the heat shock 70 protein family, has been shown to contribute to carcinogenesis. The small molecule inhibitors of mortalin-p53 interactions have been shown to reactivate p53 yielding apoptosis/growth arrest in cancer cells. Therefore, abrogators of mortalin-p53 interaction have emerged as possible new therapeutic anticancer reagents.
Methods: We performed chemical library screening based on the imaging of mortalin-p53 interaction, leading to the …

Gene-By-Environment Expression And Calculation Of The Frailty Index, Eron G. Manuosv, Vincent P. Diego, John Blangero, Michael C. Mahaney, Sarah Williams-Blangero
Research Symposium
Background: Frailty can be described as a phenotype (e.g., sarcopenia, reduced grip strength, decreased VO2 max) or as a ratio of deficits, i.e., a Frailty Index (FI). FI predicts survival, death, cognitive impairment, falls, and hospitalizations. Frailty is influenced by both genes and environment. We calculated the FI as the sum of measured deficits divided by the total number of items assessed in a pedigree-based sample of 1,029 Mexican Americans participants in the San Antonio Family Heart Study. We performed a novel search for genotype-by-environment interactions (GXE) influencing FI. Such interactions lead to heritable differences between individuals in their responses …

Antibody Mediated Targeted Drug Delivery System To Improve Immunotherapy In Pancreatic Cancer, Poornima Devi Shaji, Meena Jaggi, Murali M. Yallapu, Subhash C. Chauhan, Sheema Khan
Research Symposium
About 95% of tumor arises from epithelial cell lining ducts known to be pancreatic ductal adenocarcinomas, with less than 5-7% survival rate. Unfortunately, little progress has been seen in the outcomes of patients with PDAC as tumor develops high desmoplasia and chemo-resistance to chemotherapeutic drugs, such as gemcitabine (Gem). Immunotherapy has shown promising results in cancers, except pancreatic cancer due to their characteristic fibrotic tumor microenvironment. The therapies are unable to penetrate to the fibrotic tumors leading to insufficient availability of the therapeutic drugs at the tumor site. A recently identified mucin, MUC13 is aberrantly expressed in pancreatic tumors but …

Mortaparibplus- A Novel Anticancer Small Molecule Abrogating Mortalin-P53 Interaction In Cancer Cells, Anissa N. Sari, Ahmed Elwakeel, Jaspreet K. Dhanjal, Vipul Kumar, Durai Sundar, Sunil C. Kaul, Renu Wadhwa
Research Symposium
Background. The cessation of tumor cell growth through cell cycle arrest and apoptosis is determined by p53, a tumor suppressor protein. However, the interaction between mortalin-p53 within cytoplasm/nucleus leads to the inactivation of p53 transcriptional activation function. The disruption of mortalin-p53 complex has been suggested as an approach for developing a potential anticancer drug.
Methods. A screening of a high-content chemical library was performed to determine a molecule with mortalin-p53-interaction disrupting characteristics. After four-rounds of visual assays, we discovered a triazole derivative (4-[(1E)-2-(2-phenylindol-3-yl)-1-azavinyl]-1,2,4-triazole, named MortaparibPlus) with a potential ability of disrupting mortalin-p53-complex. In this study, we recruited …

In the genetically epilepsy prone rat, an increase in GABA neurons in the inferior colliculus increases seizure susceptibility. In contrast, Parkinson’s Disease is associated with altered GABA expression in the substantia nigra. The purpose of this study is to identify patterns between the sensory and motor regions of the midbrain and to quantify a baseline of GABA neurons in these areas.
Methods: The Allen Institute’s reference atlas of the mouse and BrainMap.org was used to identify the sensory and motor areas of the …
Erk Required For Lipopolysaccharide-Induced Tlr4 Internalization In Macrophages, Sara M. Reyna, Phoebe Fang-Mei Chang
Erk Required For Lipopolysaccharide-Induced Tlr4 Internalization In Macrophages, Sara M. Reyna, Phoebe Fang-Mei Chang
Research Symposium
Background: Insulin resistance is associated with low circulating levels of lipopolysaccharide (LPS). Binding of LPS to Toll like receptor 4 (TLR4) leads to the internalization and trafficking of TLR4 resulting in activation of downstream signaling pathways. TLR4 internalization in macrophages leads to the activation of pro-inflammatory signaling pathways and production of factors linked to the development of insulin resistance. The extracellular signal-regulated kinase 1 and 2 (ERK1 and 2) are activated downstream of TLR4 and are associated with insulin resistance. We hypothesized that ERK1 and ERK2 regulate TLR4 internalization in macrophages when exposed to LPS.
Methods: We examined whether inhibition …

Synaptic plasticity is the ability of the brain to make changes and the changes occur at synapses. To achieve the complicated functions, a good number of proteins are present at synapse and are called synaptic proteins. To stabilize these proteins at synapses, proteins are modified through posttranslational modifications (PTMs). The most studied PTMs include phosphorylation, acetylation, ubiquitination, glycosylation, palmitoylation, etc. Palmitoylation is a type of lipid modification and has received more attention recently for its contribution to protein trafficking, localization, and interaction in various synaptic plasticity. The membrane-associated guanylate kinase (MAGUK) family includes PSD-95, PSD-93 (also known as chapsyn-110), SAP102, …

Background: Cervical cancer (CC) is one of the most common gynecological malignancies in the world, and human papillomavirus (HPV) infection is the most important risk factor for their development. Although there are methods for the early detection of CC and HPV infection, but there are not highly sensitive and specific, for it´s necessary to investigate alternatives such as miR-34a and MALAT1, implicated in the pathogenesis of CC. The objective was to evaluate the association of HPV status, viral load, the presence of coinfections, and the grade of CC precursor lesions with miR-34a and MALAT1 expression in patients with high …
